Help required with identifying a component

Hi folks,

The digital display on my motorcycle recently failed. ( the display powers up and the back light comes on but none of the readings display)
After researching on a bike related forum the issue is due to corrosion on the circuit board which can be resolved by a clean up in lucky cases or a replacement of damaged components in bad cases

In my case the clean up did not work. I believe i have located the parts in question but not being an electronics expert i'm having trouble identifying them and working out what suitable replacements I need to buy.

From what I understand the parts are surface mount diodes.
I have inspected the parts with a magnifying glass and can see the following item number :

S
1G
72

I've searched online and can find anything that matches this part number. Unfortunately i'm not able to find out the manufacturer.

The guys on the bike forum have said that its a general purpose diode with around a 1 amp capability which does not need to be fast switching or high voltage. I've attached a pic below showing one of the components. ( the other one has already been removed)

Is anyone able to help me identify the part and advise me on some replacement or alternate parts that i can get hold of in the UK which I can use to try and repair the board?

Without a better pic of the component i can not verify 100%, however the S1G would be a callout for a 1A 400V Diode across many suppliers including Vishay and On Semi. 72 is likely a date code. Here is a cutout from a Vishay series and their symbol S1G. No their marking would be SG so it is likely not a Vishay part, however that would be the direction I would be looking.

Same from Diodes inc.

Have you tested the diodes?
It looks as if you have plenty of room to fit diodes with leads,. 1N4004 to 1N4007.As cheap as chips:)
 
I tested the diode arrowed in the pic and it checked out okay.

i was not able to get the probes on the other one as the legs were completely corroded away.
